Description

Technical Field

[0001] This utility model relates to the field of plastic sheet production technology, specifically to a raw material mixing device for plastic sheet production. Background Technology

[0002] Plastic granules are granules processed from waste plastics. After being mixed with other materials, plastic granules can be used to make lunch boxes, etc. A plastic mixer is a device that uses the principle of rapid rotation to mix plastic granules evenly.

[0003] A search revealed that patent application number 202420857409.4 discloses a raw material mixing device for plastic sheet production, comprising an upper mixing body and a lower mixing body. The lower mixing body is engaged with the bottom of the upper mixing body, and a stirring motor is fixedly installed in the middle of the bottom of the lower mixing body. The output end of the stirring motor passes through the lower mixing body and is fixedly connected to an active connecting shaft. This utility model discloses a raw material mixing device for plastic sheet production. Users can inspect and maintain the internal structure of the device by separating the upper and lower mixing bodies. The active connecting shaft is connected to a driven connecting shaft. The stirring bars on the driven connecting shaft facilitate mixing of materials in the upper mixing body, while the stirring blades on the active connecting shaft facilitate mixing of materials in the lower mixing body. When users need to replace the stirring bars, they can simply separate the driven connecting shaft from the active connecting shaft. The operation is simple and convenient.

[0004] In existing technologies, although material mixing is achieved through specific component configurations, the transmission architecture based on direct motor drive has an inherent drawback of high power transmission loss. Furthermore, the single-cavity mixing mode struggles to create a multi-dimensional turbulent flow field, easily leading to localized agglomeration and mixing dead zones when dealing with solid granular materials with significant particle size differences and poor flowability. Especially in mixing conditions involving high filling ratios and complex multi-component systems, the traditional solutions' overall performance in terms of mixing efficiency, energy consumption ratio, and batch stability can no longer meet the demands of modern precision processing for improved quality and efficiency. A technological breakthrough is urgently needed through structural innovation and transmission optimization. In addition, most existing raw materials are solid particles, requiring not only appropriate mixing but also a certain degree of crushing.

[0005] Therefore, we propose a raw material mixing device for the production of plastic sheets. Utility Model Content

Thus, it can achieve efficient crushing and mixing of materials, solving the problem that existing equipment is unable to efficiently mix raw material granules according to needs.

[0028] The raw material mixing equipment for plastic sheet production, through the arrangement of various components inside the mixing cylinder 1, can perform extrusion crushing and mixing of solid granular materials by downward driving, ensuring the mixing effect. At the same time, the mixing seat 2 can be driven by the bottom drive motor 9 to drive the stirring frame 16, so that it can perform secondary rotation drive on the material leaking from the sieve 15 inside the mixing seat 2, thereby achieving efficient crushing and mixing of materials, solving the problem that existing devices are unable to efficiently mix raw material granules according to requirements.

[0029] Example 2:

[0030] A column cylinder 11 is fixedly connected to the bottom end of the output shaft of the hydraulic cylinder group 6. Three sets of support columns 12 are fixedly connected to the bottom surface of the column cylinder 11, and bearing rings 13 are fixedly connected to the bottom ends of the three sets of support columns 12. The column cylinder 11 and the support columns 12 are configured to move downward under the drive of the hydraulic cylinder group 6 to assist the spinning disc 7 in rotating accordingly, stirring and squeezing the material inside the mixing cylinder 1, and ensuring the mixing effect.

[0031] A lead screw cylinder 14 is fixedly connected to the inner side of the bearing ring 13, and a spinning disc 7 is fixedly connected to the bottom end of the lead screw cylinder 14. The lead screw cylinder 14 is fitted on the outer side of the lead screw shaft column 8. The lead screw cylinder 14 is configured to rotate in coordination with the bearing ring 13 during the downward movement driven by the hydraulic cylinder group 6, and synchronously drive the spinning disc 7 on the bottom side to rotate and move downward. This not only performs rotary stirring of the material, but also allows it to be squeezed downwards to ensure the crushing and mixing effect.

[0032] The spinning disc 7 includes an inner disc and an outer ring, and ten sets of pressure plates are fixedly welded between the inner disc and the ring in an oblique distribution. The material of the spinning disc 7 is designed to facilitate its rotation, and the pressure plates enable it to perform spinning crushing and efficient mixing of the material on the bottom side when it is driven to rotate.

[0035] The working principle and usage process of this utility model are as follows: When the device is required to work, the material is fed into the mixing cylinder 1 from the feed port 4. The hydraulic cylinder group 6 inside the cylinder drives the spinning disc 7 to rotate downward along the screw shaft 8, thereby crushing and mixing the solid particles on the bottom side in a corresponding rotating manner. At the same time, during the downward pressing process, the material can also be squeezed downward from the sluice plate 15 and squeezed into the inner side of the mixing seat 2. Then, the drive motor 9 drives the stirring frame 16 to stir and mix the material a second time. Finally, the discharge pump 10 automatically discharges the material to ensure the mixing effect.
